Problems solved by technology

[0004] Due to the above situation, the circuit breaker operating mechanism is monitored and diagnosed based on the electrical signal, vibration signal, acoustic signal and image signal data of the circuit breaker operating mechanism, but there is no monitoring and management system for a large number of circuit breaker operating mechanisms on the market
In addition, if the information of each circuit breaker operating mechanism in a scattered arrangement is directly transmitted to the monitoring and management information system, the wiring method is complicated and the system construction is difficult if the wired method is used, and more communication resources are occupied and the communication cost is high if the wireless method is used.

Embodiment Construction

[0034] Such as figure 1 As shown, the present invention provides a circuit breaker operating mechanism monitoring system, which is used for remote monitoring of several scattered circuit breaker operating mechanisms. The system includes a monitoring center, one or more partition monitoring terminals, and a plurality of circuit breaker operating mechanism local monitoring systems . The monitoring system of the present invention will be described in detail below.

[0035] The monitoring center is used to centrally control the vibration sensor, acoustic wave sensor, electrical signal sensor, image sensor and their operating status information in the operating mechanism of the circuit breaker, and collect and manage the monitoring center of the operating mechanism of the circuit breaker.

[0036] The partition monitoring terminal is connected with the monitoring center and the circuit breaker operating mechanism local monitoring system of several scattered circuit breaker operati...

Abstract

The invention discloses a circuit breaker operating mechanism monitoring system and method. The monitoring system comprises a monitoring center, partition monitoring terminals and the like, wherein the monitoring center is used for conducting centralized management and control on vibration sensors, sound wave sensors, electric signal sensors and image sensors in circuit breaker operating mechanisms and running status information of the vibration sensors, the sound wave sensors, the electric signal sensors and the image sensors, and used for collecting and managing the status of the circuit breaker operating mechanisms, and the partition monitoring terminals are used for conducting centralized collection, analysis, evaluation and storage on data of the distributed circuit breaker operating mechanisms within a certain area and forwarding the data to the monitoring center in a preset mode, and used for forwarding a monitoring instruction issued by the monitoring center to the circuit breaker operating mechanisms. According to the circuit breaker operating mechanism monitoring system and method, the distributed circuit breaker operating mechanisms can be effectively and conveniently monitored, the running reliability of the circuit breaker operating mechanisms is improved, the running and maintenance cost of circuit breakers is reduced, and the data storage loads of the monitoring center are reduced.

Description

technical field [0001] The present invention relates to a monitoring system and a monitoring method, and more specifically relates to the technical field of a circuit breaker operating mechanism monitoring system and a monitoring method. Background technique [0002] The original CIGRE13.06 statistics show that more than 70% of circuit breaker failures are mechanical in nature. In 2008, among the equipment failures caused by the State Grid Corporation's 72.5kV and above voltage level circuit breakers due to their own reasons, the failures caused by the operating mechanism (including the transmission link) and auxiliary components accounted for 75.5%. Most of the mechanical defects of circuit breaker operating mechanism and transmission components can be reflected by the change of mechanical characteristics. [0003] It is difficult to fully describe the operating mechanism of the circuit breaker due to the limitation of the inherent thinking mode in the existing testing tec...
